PLOW.

QPECIFICATION forming part of Letters Patent 1\To.3l5,027I dated July 6, 1886.

l Application filed March l5, 1886. SeriallNo. 195,258. (No model.)

To alt whom it may concern:

Be it known that I, THADDEUs W. BoYLE, a citizen of the United States, residing at Augusta, in the county of Richmond and State ot Georgia, have invented certain new and 'useful Improvemcntsin Plows,of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in plows; and the objects of my improvements are to combine with the wrought-iron footstock of a shovel-plow a cast-iron standard or attachment carrying a mo1d-board and point, and secure said standard adj ustably to the side of the plow-beam and foot-stock with the same bolts that are already provided for securing a plow-shovel to the foot-stock and the latter to the beam. I attain these objects by the construction `illustrated in the accompanyingy drawings, in which- Figure l is a front perspective view of a plow constructed in accordance with my invention. Fig. 2 is a rear perspective view of the same, taken with the plow lying on its side. Fig. 3 is a perspective view of the washer used upon the bolt passing through the upper p0rtion of the standard. Fig. 4 is a perspective view of the washer upon the heel-bolt of the footstock and standard. Fig. 5 is a modication of the same.

A represents the beam, and B the handles, united together by means of the bolts a. To the beam is secured the foot-stock consisting, preferably, of two parallel flat bars, C, of wrought-iron, suitably bent to embrace the sides of the beam, and bolts d and d2 are made to pass through said bars C immediately above and under the beam. The foot-stock is further secured to the beam by a back brace, O2, pivoted at one end to the ilat bars of said footstock, and secured at the other end to the rear of the beam by a bolt, c2. The slotted rear end of the brace C2 may be provided with transverse seri-ations to receive a serrated washer, as shown in Fig. 3.

The above-described construction represents the frame of a shovel-plow, and the foot-stock carries between its flat barsOthe heel-bolt D, and nut D2 thereon, by which the shovel is usually secured to the foot-stock. To transform this shovel-plow into a mold-board plow,

of the foot-stock and beam is secured a inoldboard attachment or standard, E. The lower end of this standard is provided at its front edgewith a foot, E', to which are secured the plow-point E'I and the Inoldboard E, and to the side is secured thelandside EL. From the inner side of the standard, and in the rear of the foot E', projects a shelf, e, upon which rests the lower end of the foot-stock. In the upper end of the standard there Ais an out- Ward bend or offset, c', or it may be an opening,to allow one of the bars C of the foot-stock to pass through. The face of this offset has a series of horizontal corrugations with a vertical slot across them, through which passes the bolt d2, that also secures the foot-stock to the beam, and upon this bolt is placed a washer, d3, having a series of transverse grooves that can interlock with the corrugations in the face of the offset, and a nut retains all these parts together.

To secure the lower portion of the attachment or standard Eto the foot-stock C, the rear part of said standard may be provided with a perforation; but in place of it,to simply facilitate the molding of said standard at thatpoint, it is provided with two contiguous lugs, e?, between which the heel-bolt D is made to "pass, and to prevent said heel-bolt from movinglaterall y out from between the lugs e2, the washer D3 upon said bolt is either provided with a hooked lug, di Fig. 4, to engage with the rear edge of the standard, or, as shown in Fig. 5, with lugs d",made to cnterinto recesses formed into the rear face of the lugs e2,- and thus, although the standard E is firmly secured to the foot-stock and beam, the latter can be adjusted in its relation to the foot-stock and beam so as to run deep or shallow by means of the retaining-bolts c2, d, d2, and D, that are also used as adj usting-bolts.

Having now fully described my invention, I clairn- 1. rIlhe combination of a plow-beam and a standard bearing against the side of said beam and a bolt passing through said standard and a footstock, C, serving as a fastener and brace for said standard, substantially as and for the purpose described.

2. The combination of a plow-beam and a IOO standard bearing against the side of said beam and provided with an oiset, a slot in said offset, and a boit passing through said offset, whereby it is adapted to receive a branch of a foot-stock, substantially as described.

3. The combination of a p1owbeam anda standard bearing against the side of said beam and having its lower portion provided with a shelf, e, whereby it is adapted to receive the toe of the foot-stock @,to rest upon said shelf, substantially as and for the purpose described.

4. The combination of a plow-beam and a standard bearing against the side of said beam and having a pair of contiguous lugs, or its described equivalents, at the rear thereof, and a heel-bolt, whereby the latter is adapted to connect the standard with the foot stock, substantiaiiy as described.

5. The combination of a plow-beam and a standard bearing against the side of said beam, 2o

. heelbolt passing th rough said washer, whereby said boit is also adapted to engage with a footstock, substantially as described.

In testimony whereof I aiix my signature in presence of two witnesses.
